Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The 4.989" inner diameter fit perfectly on my homebrew kettle's lid gasket. These red silicone rings feel noticeably more pliable than the black ones I've used before, and the 70 durometer holds a great seal under pressure.

Amelia ★★★★★

The high temperature rating is exactly what I needed for my engine rebuild, and the 70 durometer feels solid without being too stiff. These fit perfectly where the old ones failed, and the red color makes them easy to spot during assembly.

Madison ★★★★★

Finally got around to replacing the old o-rings in my pressure cooker's lid, and these fit perfectly thanks to the exact 4.989" ID measurement. The silicone feels more durable than the black ones I used before, and the red color makes it easy to spot during assembly.
